Amount
Specifies the amount of sharpening applied by increasing contrast around the edges.
Radius
Controls the number of pixels to adjust around each edge. Higher values increase the number of
sharpened pixels and tend to bring out coarser detail, while lower values reduce the number of
sharpened pixels and tend to bring out finer detail.
Mask
Allows the targeting of edges, while suppressing the sharpening of noise and texture. To view the
areas the mask affects, press the ALT key when moving the mask slider. Areas affected by sharpening
appear white.
Detail
Suppresses the halo, (the light border that forms around edges with extreme sharpening), by reducing
its intensity. The higher the value, the stronger the reduction.
Threshold
Specifies how different the pixel lightness values within an edge must be before the pixels within the
edge are sharpened. Higher values sharpen only stronger edges but minimize the appearance of noise.
Lower values sharpen both strong and weaker edges, but can increase the appearance of noise. We
recommend you set the threshold to enhance edges while keeping background noise to a minimum.
You can right-click a slider to reset to the default value.
